Serb radical quits as speaker
Tomislav Nikolic quits soon after EU and Nato voice concern at his election.
Cabinet struggle
Nikovic was elected speaker after the Radicals became the largest party in parliament in general elections in January but failed to win an outright majority.
His resignation opens the way for a parliamentary vote on the new coalition cabinet, which consists of pro-Western Democrats led by Boris Tadic, the president, and the Democratic Party of Serbia, headed by Vojislav Kostunica, who is regarded as moderately nationalist.
In his resignation speech, Nikolic warned the new cabinet that if it “peacefully accepts” independence for Kosovo, his Radical party “won’t sit calmly and wait”.
Serbia’s political parties face a Tuesday deadline to form a coalition or hold new elections.
